Beschreibung

The TS30011 (1A), TS30012 (2A) and TS30013 (3A) are DC/DCsynchronous switching regulator with fully integrated powerswitches, internal compensation, and full fault protection. Theswitching frequency of 1MHz enables the use of small filtercomponents resulting in minimal board space and reducedBOM costs.The TS30011/12/13 utilizes current mode feedback in normalregulation PWM mode. When the regulator is placed instandby (EN is low), the device draws less than 10uA quiescentcurrent.The TS30011/12/13 integrates a wide range of protectioncircuitry including input supply under-voltage lockout, outputvoltage soft start, current limit, and thermal shutdown.The TS30011/12/13 includes supervisory reporting throughthe PG (Power Good) open drain output to interface othercomponents in the system.

Eigenschaften

Fixed output voltage choices: 1.5V, 1.8V, 2.5V, 3.3V, and 5V with +/- 2% output toleranceAdjustable version output voltage range: 0.9V to 5.5V with +/- 1.5% referenceWide input voltage rangeTS30013: 4.5V to 18V (20V Abs Max)1MHz +/- 10% fixed switching frequencyContinuous output current: 3A (TS30013)High efficiency – up to 95%Current mode PWM control with PFM mode for improved light load efficiencyVoltage supervisor for VOUT reported at the PG pinInput supply under voltage lockoutSoft start for controlled startup with no overshootFull protection for over-current, over-temperature, and VOUT over-voltageLess than 10uA in standby modeLow external component countmal board space and reduced BOM costs.
